602-00005

Overview

The Parallax Inc. 602-00005 is a 2-Kbit (256 x 8) Electrically Erasable Programmable Read-Only Memory (EEPROM). It features a 2-Wire I2C serial interface for data communication. The device operates within a supply voltage range of 2.5 V to 6.5 V and supports through-hole DIP-8 packaging. It functions reliably across an operating temperature range of -40°C to +85°C, with a maximum active read current of 400 µA.

Feature Summary

• Provides non-volatile data storage with 256 bytes of capacity
• Utilizes standard 2-Wire I2C serial bus protocol
• Supports wide supply voltage operation from 2.5 V to 6.5 V

Applications

• Embedded systems requiring small-scale non-volatile configuration storage
• I2C-based sensor modules needing parameter retention
• Low-power consumer electronics with limited memory requirements

Procurement Notes

Verify the specific package variant and manufacturing date code upon order confirmation. Confirm compatibility with your system's I2C clock speed and voltage levels. Check for any RoHS compliance documentation if required by your region. Ensure the DIP-8 footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when a compact, low-pin-count EEPROM is needed for I2C interfaces. It is suitable for applications requiring frequent byte-level writes or updates. Consider the DIP-8 package if through-hole assembly is preferred over surface mount alternatives. Evaluate power consumption needs against the 400 µA active read specification.

Part Context

This part belongs to Parallax Inc.'s memory product line, specifically designed for educational and hobbyist microcontroller projects. It serves as a reliable non-volatile storage solution for Basic Stamp and similar platforms. The component integrates easily into existing I2C networks without complex driver requirements.

Replacement Considerations

Direct substitutes include other 2Kb I2C EEPROMs in DIP-8 packages, such as the Microchip 24LC02B. Verify pinout compatibility and voltage tolerances before swapping. Ensure the replacement supports the same write cycle endurance and data retention specifications.
